I have a 1991 Lexus LS400. when i reclined drivers sode seat I must have put it back to far. I heard it make a popping sound. Now the seat will not raise up all the way. It will only start raising on the left side of the seat, but not on the right side.

NO JUST FILL GEARBOX LEVEL AND CHECK AGAIN AFTER RUNNING ENGINE

If you pop the back panel off your seat on the bottom right hand side you will find the motor for the recline and it has one T30 bolt and a shaft going through the center witch if you remove the clip on the right side of the shaft it will slide out far enough to remove the motor.Follow the wire down to the bottom of the seat almost to the floor the plug is there. When putting in the new motor it is easiest to have some one help you by pushing the button back and forth to line up the shaft and bolt hole.hope this helps you out.

On both sides of the headrest spokes are little adjuster rings. Adjust the headrest up to the highest position. Push down on both of the adjuster rings. While doing that, pull up on the headrest and it will pop right up.

There are 11 electronic control units(ECU) located in the dash area. They are as follows.
Engine + trans. ecu. behind right side of the dash.
Abs + traction ecu. beside the engine ecu.
electric mirror ecu. behind upper right side of dash.
SRS ecu. behind dash at console.
Shift lock ecu. in center console near shifter.
Power seat ecu. under drivers seat.
progressive power steering ecu. behind left dash left of column.
Steering column tilt + telescopic ecu. behind left dash above column.
Anti-theft ecu. behind far left of dash.
Cruise control ecu. just below the anti-theft ecu.
My guess is you are looking for the engine ECU but you may be
looking for 1 of these in the future. Hope this helps.

place a crowbar under the seats near the carpet and, pry up gently the car has clips under both sides of the center seats then: push down on the top of the seat back disengaging it

It's the top right kick panel fuse and should be a 15 amp.

sounds like you have bent something underneath or broke a support bracket

slide the lower part of shifter handle down and you will find two screws, but there is 2 wires coming in from center console for overdrive button.you have to remove the center console cover and remove the 2 wires from connector and then pull up threw handle.when you go back together you will have to guide them back threw the handle.

Hey,

just purchased a 1991 lexus LS400....

I did not realize the manual was in the car under the seat so I looked for a free download, no luck.

However I can scan and attach pages and /or answer direct questions from my manul if you would like.
